Project Echo: Single-Shot Pistol

Project Date: Mar 2011

I saw the single-shot gun design from LK Machines and wanted to create a Lego gun for myself. I'm far too lazy to come up with a gun design so just followed LK Machine's. I modified it a bit, though.

The original gun used 4 rubber bands, 2 for the trigger and 2 for launching. By adding 6 more launching rubber bands and strengthening my gun to take the extra load, the force of the bullet is increased dramatically.








As the name implies, this gun has no magazine. Each bullet has to be fed into the launching chamber from the top. This results in low rate of fire. To compensate for this, I increased the number of launching rubber bands  so that each round will hit harder. Using a 2x3 brick as ammo, each round can penetrate a sheet of paper with ease. The gun can accept 2x2, 2x3 and 2x4 bricks for ammo.

Here's the video:
